Sick Bridges: An Eagle Eye Team Special Report

Berkshire County’s Top 10 structurally deficient Bridges

Posted

The Berkshire County bridges featured here are listed by the state Department of Transportation as the 10 most in need of repair. All are structurally deficient, a status triggered by a rating of a bridge component as 4 or less (see information below on ratings). But they are not the only bridges with problems. The state is only required to inspect bridges measuring 20 feet or longer. (Twenty feet is the equivalent of 6.09 meters.) To view an online map, visit https://tinyurl.com/MassBridges.

MassDOT is working to add inspections of bridges that are 10 to 20 feet in size, but results are spotty.

Bridge ratings

Bridge conditions are rated on a 0-9 scale. A bridge is listed as structurally deficient if any of its three elements receive a rating of 0 to 4.

A rating of 0 is a failed bridge taken out of service.

Rating 1 is imminent failure, with “major deterioration or section loss present in critical structural components” and results in closing, though with corrective action the bridge can be put back in service.

Rating 2 is critical condition with “advanced deterioration of primary structural elements.”

Rating 3 is serious condition, with “loss of section (and) deterioration.”

Rating 4 is poor condition, with “advanced section loss, deterioration, spalling or scour.”

Spalling refers to deterioration in which flakes of metal come loose. Scour involves water flow that weakens the integrity of bridge supports.

The parts of a bridge are defined as the deck (the traveling surface), the superstructure (beams, trusses, etc., that hold up the deck) and the substructure (piers and abutments that hold up the superstructure).
